Good instruments are generally one of the key ingredients for a successful chromatographic separation. We manufacture a complete line of instruments for low-pressure liquid chromatography, many of which are also quite useful in hplc applications. These instruments include Peristaltic Pumps, a Fraction Collector, a fixed wavelength UV Detector, a Solvent Recycler, and a Flow Rate Controller.

The Macroflow and MP-2 pump drives are suitable for high flow rate applications while the MP-1 drive is ideally suited to low flow applications. The Fast-Load pump head allows the tubing to be replaced without disturbing its connection to the drive. For cost sensitive applications other, conventional, peristaltic pump heads are also available. The pumps and drives are described at http://www.spectra-chrom.com/pump.htm.

The CF-1 Fraction Collector is the ultimate chromatographic fraction collector. It can collect up to 174 fractions in 12 to 13 mm diameter tubes. The unique design with a stationary drop head is superior to the more common X-Y type fraction collectors; the stationary drop head can not fling drops when changing tubes. This eliminates any possibility of contamination between tubes. The CF-1 Fraction Collector is described at http://www.spectra-chrom.com/fraction.htm.

The choice of a detector can be one of the most significant in both an analytical chromatography system as well as a preparative system. The Spectra/Chrom® Model 280 UV Monitor is a fixed wavelength flow-through spectrophotometer specifically designed for use as a chromatographic detector. It features a dual beam optical system that allows the automatic subtraction of a solvent background, even in the presence of a rapidly changing gradient. Three different flow cells are available and filters for both 254 and 280 nm are included with the detector. The Model 280 UV Detector is described at http://www.spectra-chrom.com/newuv.htm.

Most chromatographic laboratories spend a large fraction of their budget on solvents, both buying the solvents and then paying to dispose of them. The S-3 Solvent Saver System is an hplc solvent recycler which significantly reduces the use of solvents in both analytical and preparative hplc. Solvent savings generally exceed 80%. The S-3 Solvent Saver System is described at http://www.spectra-chrom.com/s3.htm.
